Linear Performance Analysis

[MRasidÇ]

Good day everyone, I am going to build an additional floor in a building with an existing ground floor, for this, the municipality asked us for a Linear Performance Analysis, but when I added the additional floor, they asked me to make a system analysis before doing the analysis, and I made a DPA after I did the analysis, but in the Required Concrete Samples section of the report, the most He stated that it was as if there were 2 floors, as if we had taken samples from them, because of his writings of at least two, a total of 4 examples for the entire project, and he stated that there should be 2 for the whole project, I wonder if I am doing something wrong while doing the analysis or should it be read this way in this report. I would be very happy if you could help.

Hello, That article in the report is the sentences written in the limited or comprehensive evaluation headings in the regulation. No need to get stuck in that part. There should be a signed lab result showing the locations and results of the cores. Just add this to the beginning of the report. The analysis of the sentence written there does not have a binding feature.

Thank you

Hello My suggestions; Calculation order, --Do what is required to be done in the existing building according to TBDY2008 Chapter 15, --Enter the column-wall-beam-foundation dimensions, the concrete value, the reinforcements for which you have determined the current situation, and fix the column-wall-beam-foundation reinforcement. --Enter the data of the second floor, make an earthquake calculation without fixing the column-wall-beam on this floor, check whether the foundation carries the floor you added in this calculation, --Fix the reinforcements on the added floor, (The entire building is fixed.) --Performance have the analysis done, --If it doesn't give an error, it's ok, --If the performance analysis gives an error, repeat the performance analysis by putting an extra screen in both directions.

hi, in the regulation for performance analysis, it says "if there is a brittle element, on condition that it is strengthened...." What to do in this situation? Because in every building, there is necessarily a crunchy element.

I know that the reinforcement cannot be on an element basis.

Hello, you know wrong. The reinforcement of the elements that do not provide shear safety or the elements that will receive "brittle damage" due to the lack of security in the column-beam junction is made on element basis. Brittle You will strengthen all the elements that you think will be damaged with fibrous polymer or mantle. This is already the work to be done. If your structure already achieves the performance level you aim for, except for the elements that will get brittle damage, you do not need to do anything else. If it does not, then additional reinforcement to achieve the performance level you targeted or adding a new element (like curtain) is coming.

Mr. erhan, is there a standard for the application we will make to the crispy elements?

Hi My Suggestions; Order of calculation, --Do what is required to be done in the existing building according to TBDY2008 Chapter 15, --Enter the column-wall-beam-foundation dimensions, concrete value, reinforcements and column- Fix the reinforcement at the curtain-beam-foundation. --Enter the data of the second floor, make an earthquake calculation without fixing the column-wall-beam on this floor, check whether the foundation also carries the floor you added, --Fix the reinforcements on the added floor, (The entire structure is fixed.) --Have a performance analysis, --If it doesn't give an error, it's ok, --If the performance analysis gives an error, repeat the performance analysis by putting an extra screen in both directions Ünver ÖZCAN

Thank you

Hello.. I had a few questions about the performance analysis, I would be very happy if there are friends who may be interested.. - According to the results of the core, the average concrete class is C9, but there are also columns with c7 c8 c11 c12. Should I get the average value? - Will reinforcing the brittle elements be enough for me to switch to controlled damage or will I have to provide shear safety in the column-beam junction?

Sir, I need your help

Hello.. I had a few questions about performance analysis, I would be very happy if there are friends who might be interested.

I am adding 4 additional floors to the ground+3 storey building. It makes me suspicious that it provides Controlled Damage, albeit by reinforcing the columns with C9 concrete. Will this massive mass really be able to carry Ground+7 floors with the C9?

 

[Levent Özpak]

I'm adding 4 additional floors to the ground+3 storey structure. It makes me doubt that it can provide Controlled Damage even by reinforcing the columns with C9 concrete. Can this massive mass really support Ground+7 floors with C9?

If you add it, we'll review it.

Good afternoon everyone, I am going to build an additional floor in a building with an existing ground floor, for this the municipality asked us for Linear Performance Analysis, but when I added the additional floor, they asked me to do a system analysis before doing the analysis, the program made a DPA from me and I did it. However, in the Required Concrete Samples section of the report, he stated that it was as if there were 2 floors, as if we had taken samples from them, due to the writing of at least two samples for each floor and a total of 4 for the whole project, and he stated that there should be 2 pieces for the whole project, I wonder if I was doing something wrong while doing the analysis. I'm doing it or is it supposed to be read this way in this report. I would be very grateful if you could help.

Hello

--Enter the column-wall-beam-foundation dimensions, the concrete value, the bars and the column-wall-beam-foundation rebar fixing do.

Your project is stuck here. Do what I wrote above without skipping a line. Unver ÖZCAN

Unver Bey took core from the laboratory building. He bought it only for the colon, and he did this in consultation with environmental urbanism. Therefore, I fixed the column reinforcements according to the laboratory results. I entered the column beam dimensions exactly. I removed the reinforcement fixing on the floors to be added to the top, I made the concrete values 25 on the existing floors, C9 on the additional floors.

 

[huseyinakkus56]

--Do what is requested in the existing building according to TBDY2008 Chapter 15,

I'll look into that

 

[unver]

Hi You did not fix the accessories. In fixing the reinforcement, you must tick the places I have shown in black (COLUMN-BEAM-CURTAIN-FOUNDATION). If you do not put Tiki, as I marked with red, the program calculates and changes the reinforcement and Purs, it will be irrelevant to the value you entered. Unver ÖZCAN

 

[huseyinakkus56]

I'm correcting it now, I think I skipped the ground floor.

 

[unver]

The same is true for all existing floors.
